i Application le. September 12 1919. Serial No. 323,254-,

To all 107mm it may concern Be it known that I, HERBERT O. TOMLIN- soN acitizen of the United States, residing at li/Vheaton, State of Illinois,have invented a new and useful Improvement in Semi -Indirect- LightingDevices, of which the following is a specication.

This invention relates generally to electric-light fixtures and has forits object the provision of a fixture including a support or holder foran electric-light diffusing bowl or globe, which is simple inconstruction and ornamental in use.

Another object is to provide a fixture of this character with a holderwhich shall be largely concealed from view below and which shalleffectively support the light diffusing bowl in a manner to afford readyremoval of suoli bowl from the fixture without the disengagement of theholder from the shade.

With these and other objects in view, my invention consists in the novelconstruction, combination, and relative position of the parts Vandmembers hereinafter described and shown in the accompanying drawings,and particularly pointed out in the appended claims.

A structure embodying my invention is illustrated in the accompanyingdrawings, in which Figure 1, is an elevation showing Figs. 2 and 3 arerespectively, side elevation and plan view of my improved bowl holder,and Fig. l isan enlarged detail in sectional view showing the attachmentof the holder to the edge of the shade or reflector.

Referring to the illustrations, 10 indicates an incandescent electriclamp which is carried in the well known socket 11. A reflector or shadesupport 12, comprising a split ring 12A encircling the socket 11 andhaving a binding screw 13 for clamping the ringl to the socket, isprovided with thecutstanding annular flange 12D with radially arrangedscrews 14C for releasablyr engaging the annular iiange 15A of the shadeor reflector 15, which preferably is of white or opal glass. In this waythe reiiector 1s removable by downward disconnectlon from saidsupporting means therefor. i I have preferred to show the reflector 15of a iiat downwardly flaring form.

The `diffusing bowl 16, is preferably o translucent ground glass and maybe of any in the county of Dupage and v suitable shape or color. 16A isformed bowl.

To supportthe bowl 1G below the refiector 15, I provide a support 17which comprises preferably three downwardly diverging spring-like metalarms 17A which areVV provided with hooked-ends 17B adapted to engage anypoints on the flange 16A to retain the bowl. The bowl is rotatable, ofcourse, 1n these hooks, so that it can be insertedl and removed in of.Near their upper ends 17C the arms V17A are held in spaced relation by aring 17D which is welded, or in any'other way. attached -to the arms. dformed in a compound curve, and are outwardly disposed in a manner to yaiiord spring-like hooks which engage over the upper edge 'of thereflector and thus support the bowl therefro It will be observed thatthe holder need not be disengaged from the reflector to permit theremoval ofthe-bowl, but that it is only required that one of thespring-arms 17A be unhooked from thebowl iiange to permit the bowl to bereadily removed from the other two supporting arms. Also, by reason ofthe fastening' means 13 the reiiector and bowl and the supporting meanstherefor may be removed intact from the lower end of the socket. will beseen, permits the ring 12A to be removed from the lower end of thesocket, even when the lamp is in place, and if this is; done the lampcan then be unscrewed, very obviously, after such removal of the bowland reflector as a unit from the lower end of the socket.

It will be seen that the rigid ring 17D fits snugly within the openingin the upper portion of the reiiector 15, so that the upper end portions17E of the spring-y arms overhang the edge of said opening, whereby thebowl is firmly supported below the reflector. These springy upper endportions 17E a-re sprimg inwardlyl when forced upwardly A suitableflange -through the opening in the reflector while the lower endportions 17B` are sprung outwardly to receive the annular upper edge ofthe bowl. Thus the bowl support is resiliently engageable with anddetachable from the upper and inner edge of the reflector and is alsoresiliently engageable with and detachable from the rim or upper edge ofthe bowl, but the' rigid ring 17D holds the aroundthe upper edge` of theThe lamp 10, it`
